PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.198) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
object is high, a warning
operates to urge the driver
to take evasive action and
the potential brake pressure
is increased to help the
driver avoid the collision. If
the system determines that
the possibility of a collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.207)
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving.
Never use the pre-collision
system in place of normal
braking operations. This sys-
tem cannot help avoid or
reduce the impact of a colli-
sion in every situation.
Over-reliance on this system
to drive the vehicle safely may
lead to an accident resulting
in death or serious injury.
●Although the pre-collision sys-
tem is designed to help avoid or
help reduce the impact of a col-
lision, its effectiveness may
change according to various
conditions. Therefore, it may not
always be able to achieve the
same level of performance.
Read the followin g items care-
fully. Do not overl y rely on this
system and always drive care-
fully.

■Pre-collision warning
When the system determines
that the possibility of a collision
is high, a buzzer will sound and
an icon and warning message
will be displayed on the
multi-information display to urge
the driver to take evasive action.
If the detectable object is a vehi-
cle, moderate braking will be
performed with the warning.
If the system determines that
the accelerator pedal is strongly
depressed, the following icon
and message will be displayed
on the multi-information display.
■Pre-collision brake assist
If the system determines that
the possibility of a collision is
high and the brake operation by
the driver is insufficient, the
braking power will be increased.
■Pre-collision brake control
If the system determines that
the possibility of a collision is
extremely high, the brakes are
automatically applied to help
avoid the collision or reduce the
impact of the collision.
■Emergency steering assist
If the system determines that
the following conditions are met,
assistance will be provided to
help enhance vehicle stability
and prevent lane departure.
During assistance, in addition to
the pre-collision warning, the fol-
lowing icon will be displayed on
the multi-information display.
The possibility of a collision is
high
There is sufficient space
within the lane to perform
evasive steering maneuvers
The driver is operating the
steering wheel
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.

■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.

At an intersection, etc., if the
system determines that the pos-
sibility of a collision with an
approaching vehicle or motorcy-
cle is high, the pre-collision
warning and pre-collision brak-
ing will operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
■Acceleration Suppression
at Low Speed
When driving at a low speed, if
the accelerator pedal is strongly
depressed and the system
determines that there is a possi-
bility of a collision, engine output
will be restrained or the brakes
will be applied weakly to restrict

WARNING
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●The pre-collision braking func-
tion is not designed to hold the
vehicle stopped. If the vehicle is
stopped by pre-collision brake
control, the driver should oper-
ate the brakes immediately as
necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●If the brake pedal is being
depressed, the system may
determine that the driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision brake control.
■Acceleration Suppression at
Low Speed
If the steering wheel is being
turned, the system may determine
that the driver is taking evasive
action and possibly prevent the
Acceleration Suppression at Low
Speed function from operating or
possibly causing its operation to
be canceled.
■Emergency steering assist
●The emergency steering assist
will be canceled when the sys-
tem determines that lane depar-
ture prevention control has
completed.
●Depending on operations per-
formed by the driver, emer-
gency steering assist may not
operate or operation may be
canceled.
• If the accelerator pedal is depressed strongly, the steering
wheel is turned heavily, the
brake pedal is depressed, or the
turn signal lever is operated, the
system may determine that the
driver is taking evasive action
and the emergency steering
assist may n ot operate.
• While the emergency steering assist is operating, if the accel-
erator pedal is depressed
strongly, the steering wheel is
turned heavily, or the brake
pedal is depressed, the system
may determine that the driver is
taking evasive action and emer-
gency steering assist operation
may be canceled.
• While the emergency steering assist is operating, if the steer-
ing wheel is held or turned in the
opposite direction of system
operation, emergency steering
assist operation will be can-
celed.

■Operating conditions of each function of the pre-collision system
The pre-collision syst em is enabled and the system determines t hat the pos-
sibility of a frontal c ollision with a detected object is high.
However, the system will not operate in the follo wing situations:
●When the vehicle has not been driven a certain amount after a t erminal of
the battery has been disc onnected and reconnected
●When the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
The following are the operational speeds and cancelation condit ions of each
function:
●Pre-collision warning
While the pre-collision warning is operating, if the steering w heel is operated
heavily or suddenly, the pre-co llision warning may be cancelled.

Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising:
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration:
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off:
If a preceding vehicle stops, the vehicle will also stop (contr olled
stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-u p
cruising (start off operation). If a start off operation is not per-

(If the vehicle has been stopped by
system control, depressing the
brake pedal will not cancel control.)2Press the “RES” switch to
resume control.
Each time the switch is pressed , the vehicle-to-vehicle distance set-
ting will change as follows:
If a preceding vehicle is detecte d, the preceding vehicle mark will be dis-
played.
The actual vehicle-to-vehicle di stance varies in accordance wit h the vehicle
speed. Also, when the vehicle is stopped by system control, it will be
stopped at a certain distance from the preceding vehicle, depending on the
situation, regardless of the setting.
■Operating conditions
●The shift lever is in D.
●The desired set speed can be set
when the vehicle speed is approx-
imately 20 mph (30 km/h) or more.
• If the vehicle speed is set while driving at below approximately 20
mph (30 km/h), the set vehicle
speed will be approximately 20
mph (30 km/h). • If the vehicle speed is set while
driving at a speed that exceeds
the system’s upper limit, the set
vehicle speed will be the system’s
upper limit.
■Accelerating after setting the
vehicle speed
As with normal driving, acceleration
can be performed by depressing the
accelerator pedal. After accelerat-
ing, the vehicle will return to the set
